The guilt of yelling

I lost it. I lost my cool and yelled at my 3-year-old daughter, Sophie. The guilt is not really because of the yelling but because I know the real reason I yelled was purely cos I was dealing with my own anger and she stepped on my tail, somehow. Oh gawd, the fear in her eyes when I yelled and the burst of tears as she cried her fears out. The guilt and resentment towards myself hit me so hard. If I yelled because she did something wrong, it was justified and I won't feel the guilt. Probably the anger and disappointment but definitely not the guilt. But now it's just loads of guilt and resentment and tears. We apologized to each other and made up but I know the fear is still there. I'm afraid of myself too. I really lost control this time and that made me really scared. What will I do after delivery of Stephan? 😭
